TOOL-HANDLE.

SPECIFICATION forming part of Letters Patent No. 758,825, dated May 3,1904.

Application filed October 21, 1903- Serial No. 177,887. (No model.)

To (all whom, it may concern:

Be it known that I, MAsoHIL D. CONVERSE, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented new and useful Improvements in Tool-Handles, of which thefollowing is a specification.

My present invention relates to tool-handles, and more particularly tocompass-saw handles.

It comprises a recessed tool-handle having the flanges at the lateralmargins of the recess, each pierced by a hole tranversely thelongitudinal plane of the handle at a proper level above the bottom orbed of said recess, and a wire bolt rotatably entered therethrough andbent to form a cam or a cam and a lever for its manipulation; and itsobjects are to improve the efliciency and cheapen the cost of handlesfor compass-saws and for other tools to which the same may be adapted,all which, with the principles, construction, and operation of the same,will hereinafter be more clearly set forth and distinctly claimed.

1n the drawings, Figure 1 is a side elevation of my improvedtool-handle, illustrating its adaptation to compass-saws; Fig. 2, asimilar view showing the compass-saw removed; Fig. 3, an end viewshowing crosssection of saw-blade on line 1* .r; and Fig. 4, a similarview showing saw -blade removed, which several views show theprinciples, construction, form, and operation of my invention.

Like characters indicate corresponding parts throughout the severalfigures.

A is ahandle-bodyofknownlink-like form, but which may be of any formsuitably recessed or socketed for reception of the tool to be used andhaving each of the lateral flanges c a pierced by a hole for receptionof a wire B to form a tool securing or holding cam, and C (in thepresent instance) is a compass-saw blade.

(1 is a flattened bed onthe inside of the front end of the handle, whichforms a wall of a recess b and against which the cam bend 0 of Boperates to forcibly cramp and secure the compass-saw blade C when thecurved lever end (Z of the wire cam B is turned in the prescribeddirection.

The cam-wire B, which is preferably provided with a head at one end, isstraight originally and is first inserted and rotatably fitted throughsaid transverse holes in the flanged portions 6 e of the handle at itsforward end and on such a line as to leave a suflicient space between itand the wall a for insertion of the shank of the compass-saw or othertool, and then by suitable appliances the end (Z is bent to form alever, and at 0, between the flanges c c, this wire is also bent ordepressed, while the lever (Z is held in the position shown by Figs. 1and 3 to form a cam. (Distinctly seen in Figs. 2 and Having beenconstructed, formed, and proportioned as shown, the operation of myinvention is as follows: The cam-lever (Z of the wire cam B is turned upright-angularly to the plane of the tool-handle, as shown in Figs. 2 and4, which turns the cam bend 0 out to the position shown by Fig. 2,giving clearance in the recess Z; for insertion and adjustment of thecompass-saw or other tool-shank, which when inserted may be securelyclamped and held in the handle A by turning the camlever (Z down to theposition shown in Figs. 1 and 3, causing the cam bend c to forciblyengage and pinch the saw-blade or tool-shank against the wall or bend a.To release the saw or tool, the lever D would be returned to theposition shown in Figs. 2 and 4.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A tool-handle of the character described provided with a recess withflanges at the lateral margins of the latter each pierced by a holetransversely the longitudinal plane of the handle and on a line abovethe level of the bed of said recess, in combination with anintegrally-formed wire cam and lever entered and rotatably tittedthrough the transverse holes in said flanges.

2. A tool-handle ot' the character described provided with a recess withflanges at the lateral margins of the latter each pierced by to thisspecification in the presence of two subahhole trl'imsveirsely ithelongituldinlal pllane of scribing Witnesses. t e ianc e anc on a ineabove tie eve of the w 1 1 bed of said recess, in combination with aWire MASLHIL CONVERbE 5 cam entered and rotatably fitted through theWitnesses:

transverse holes in said flanges. FRANK S. APPLEMAN,

Intestimony whereof Ihave signed my name 0. E. WEBB.
